You must first set up an equation for this problem. Your equation is 8+3x=128. If we subtract 8 from each side we get 3x=120. If we then divide both sides by 3 we get x=40. Therefore your number is 40 because 8+3*40=128.
Answer:
Step-by-step explanation:
x=40
Simple you get the area of the inner rectangle, then the area of the 2 semi circles then add them.
First, you need to notice that the diameter of each circle is same as the side of the rectangle (46m), also not that the 2 semi circles will make a complete one circle with radius (46/2)
so now we are left with the area of the rectangle+the area of a circle with radius of 32m
The total area= (46*92)+(3.14*(32^2))= 7447.36m^2
and to keep you significant figures the answer is rounded to 3 digits, so the final answer will be 745m^2.
Hope this helps, thanks.
Answer:
in the simplest term is:

Step-by-step explanation:
Given the expression

Thus, solving to reduce to the simplest term

LCM of 15, 2: 30
Adjusting fraction based on the LCM
so the expression becomes

Apply the fraction rule: 

Add the numbers: 8+15 = 23

Therefore,
in the simplest term is:

Answer:
D. None of the above; the triangles cannot be proven similar
Step-by-step explanation:
There are no signs that shows the triangles are similar or congruent for given information. So the answer is last option :
D. None of the above; the triangles cannot be proven similar
